Bears may experience a dramatic decrease in heart rate, sometimes dropping to as low as 10 beats per minute, while respiration becomes shallow and infrequent. these physiological changes enable bears to maintain a state of dormancy while minimizing energy expenditure. 2. occasional arousals from hibernation.
